摘　　要：通过溶剂热法制备了不同锰离子掺杂量的硫化锌粉体转光剂,并利用SEM、XRD和荧光分光光度计对其形貌、组分、结构及发光性能进行了研究。结果显示,锰离子的掺入影响了硫化锌粉体的粒径,出现晶粒细化的现象。以紫外光作为激发光源,当锰的初始浓度不高于20%时,样品的发光峰通过高斯分峰可分为2个,分别位于465～475nm和570～585nm处;当锰的初始浓度高于20%时,硫化锌的发光峰消失,只出现锰的发光峰(580nm左右),即得到了预期的红色发光。Manganese ion doped zinc sulfide（ZnS = Mn） light conversion powders with different dosages were synthesized by solvothermal method. The effect of Mn doping on the component, morphology, microstructure and op- tical properties of the ZnS powders was investigated by means of scanning electronic microscope（SEM）, X-ray diffrac- tion（XRD） and photoluminescence（PL）. The results show that the growth of ZnS grains is affected by the Mn do- ping, i.e. the ZnS = Mn grains occur refinement phenomenon. The ultraviolet light was used as the excitation, when the initial concentration of manganese is not more than 20%, the experimental emission peak is composed of two peaks at 465~475nm and 570~585nm, respectively. Onee the initial concentration o} manganese surpasses 20%, the lumi nescence peak of ZnS disappears, leaving only the peak of manganese luminescence （around 580nm）, i.e. the red emission expected is obtained.
